Testo 552 digital vacuum gauge introduction
The testo 552 is a high precision electronic vacuum gauge that provides absolutely accurate and reliable measurement data. It has all the functions required for vacuum detection of all refrigeration and heat pump systems, and is extremely long standby and rugged.
Unlike other vacuum gauges, the testo 552 is the only vacuum gauge on the market that uses a maintenance-free absolute pressure sensor. This advanced sensor technology provides complete, no manual maintenance and is 100% accurate and reliable. Measurement data.
Testo 552 digital vacuum gauge application field
Vacuuming is one of the most important steps in installing or restarting an air conditioning or refrigeration system: impurity gases, water vapors, and oils need to be properly removed. At this point, it is necessary to measure the degree of vacuum in the system.
This is the original design of the testo 552 digital vacuum gauge: to provide you with accurate information on the degree of system dehumidification and impurity removal, and to measure even the absolute absolute pressure value with extremely accurate and reliable. This means that the user can always meet the manufacturer's specific requirements for the system. When the limit is exceeded, a visual alarm is issued in time.
Testo 552 digital vacuum gauge features
1. Maintenance-free absolute pressure sensor
2. High precision, extremely sturdy, super practical – large display with backlight display, and visual alarm when over limit
3. Directly measure the absolute pressure, automatically calculate and display the evaporation temperature of water
